In Plain Language

Architecture roles establish the structural blueprint of the system before coding begins. Across these seven roles, architects ensure business capabilities align with technology investments, data schemas remain secure and compliant with health privacy laws, and integration interfaces communicate reliably across hospital and enterprise networks.

Architecture Discipline Roles (7 Roles)

Architecture establishes long-term integrity, safety partitions, and technology standards across the product lifecycle. Architects ensure that business objectives, regulatory constraints, and data flow models translate into coherent technical structures. Acronyms used here include Non-Functional Requirements (NFRs), Architecture Decision Records (ADRs), and Application Programming Interfaces (APIs).

Enterprise Architect

Aligns the organization’s multi-product technology strategy with business goals, compliance mandates, and long-term tech roadmaps.
